This national historic trail extended from just north of Seward, passed through Iditarod and McGrath and then ended in Nome. The trail was 1,150 miles long and reached its peak in usage in the early 1900s when freight shippers, mail haulers, miners and passengers relied on dogsleds to reach the gold rushes of Interior Alaska. The demand for accommodations quickly resulted in a string of roadhouses and dog barns along the trail at a convenient day's journey apart, roughly 20 miles.
